In Response To: HUUUUMMMMMMMMMM (Brian Nystrom)

: I noticed this for the first time in my Pintail this past weekend. While
: surfing on open water, I noticed a moaning sound as I slipped off the back
: of waves

FYI, we used to solve the humming or thrumming sound coming from Hobie Cat rudders and the centerboard on my JY15 sailboat by shaving the trailing edge of the rudder/board to a fair knife edge. Simply used an open pair of shears like knife sharpeners, drawing them down the edge. The humming was caused by the turbulence from an un-fair trailing edge. Made the rudder or centerboard vibrate. In all cases, it wasn't caused by a loose assembly.
